Problems solved by technology

[0004] However, SVG vector graphics cannot fully meet some actual needs of power systems at present, such as trend analysis and viewing of measurement points, daily / month / year curve viewing, pie charts, bar graphs, histograms, instrument panels, LEDs and other advanced graphic elements. Convenient drawing, real-time alarm in the screen, and dynamic display of real-time data and historical data in Haixun database and other functions

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The method that a kind of SVG vector diagram of the present invention is converted into LPF vector diagram is:

[0028] Convert the SVG format configuration diagram through object conversion, convert the SVG graphic objects: line, circle, ellipse, rectangle, polyline, polygon, path and other elements into the corresponding elements in the LPF, and analyze the filter used in the elements Mirror, add special effects to shapes and text, analyze linear gradients and radial gradients in SVG, achieve smooth transitions from one color to other colors, and use multiple color transitions in the same primitive.

[0029] Then, in the converted LPF, by writing Javascript scripts, the dynamic display of the LPF can be realized, and the data and data alarms in the Haixun real-time database can be better displayed to the user through the flickering of the graphic ele...

Abstract

The invention discloses a method for converting an SVG (scalable vector graphics) into LPF (low pass filter) vector graphics. The method comprises the following steps: at first, elements of an SVG graphic object are respectively converted into elements in corresponding LPF vector graphics, filters used in the elements are analyzed, linear gradient and the radiation gradient in the SVG are analyzed, and transition of multiple colors is carried out in the same pel; then, in the converted LPF vector graphics, the dynamic picture display of the LPF vector graphics is realized through compiling Javascripts, and data and data alarm in a highsoon real-time database are displayed to a user through pel flashing and color changing manners; and the LPF vector graphics are transferred in an Oracle of an application server through a configuration tool, the user uses a portal system and opens the configuration graphics through a configuration ActiveX, and the LPF vector graphics are obtained from the application server and are displayed to the user. Under the condition that the LPF vector graphics are amplified or changed in size, the graphics quality cannot be influenced.

Description

technical field [0001] The invention relates to an XML language-based two-bit vector diagram format conversion method, which belongs to the field of view display on electric power system portal websites. Background technique [0002] SVG Scalable Vector Graphics (Scalable Vector Graphics) is a graphic format based on Extensible Markup Language (XML) for describing two-dimensional vector graphics. SVG is a new two-dimensional vector graphics format formulated by W3C, the Internet Standards Organization, in August 2000, and it is also a network vector graphics standard in the specification. SVG strictly follows the XML syntax and uses a descriptive language in text format to describe image content, so it is a vector graphics format that has nothing to do with image resolution. [0003] The SVG graphics format has the following advantages: 1. Vector display objects, not limited by resolution; 2. Based on XML; 3. Use text to describe objects; 4. Interactive and dynamic; 5. Full...
